how do you get the answer to 6.78042- 0.9427

Answer 1

To find the answer to \( 6.78042 - 0.9427 \), you can align the numbers by their decimal points and then perform the subtraction.

Here’s how it looks when you align them:

  6.78042
- 0.94270  (adding an extra 0 to keep the column alignment)
-----------

Now perform the subtraction column by column:

1. Start from the right:
   • \(2 - 0 = 2\)
   • \(4 - 7\): Since 4 is smaller than 7, we need to borrow. The 0 before the 4 becomes a 10 (so it’s actually 14), and we take 1 from the 8 (making it 7). So, \(14 - 7 = 7\).
   • \(7 - 2 = 5\)
   • \(8 - 9\): We need to borrow again. So, 6 (the 6 becomes 5) borrows 1 for the 8 making it 18. Thus, \(18 - 9 = 9\).
   • \(5 - 0 = 5\)
   • Lastly, \(6 - 0 = 6\).

Putting it all together, we get:

  6.78042
- 0.94270
-----------
  5.83772

So, \( 6.78042 - 0.9427 = 5.83772 \).
